Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Select

st.sel changed

Move

move nodes keys by d (world units); the d of one gesture add up to total; done = the gesture ended (released, a key nudge; Esc sends d = minus everything so far)

Fields

keys: Vec<u64>

d: [f32; 2]

total: [f32; 2]

done: bool

Connect

connect from -> to (port or node keys); quick = dragged out of a port with DG_SELECT

Fields

from: u64

to: u64

quick: bool

ConnectDrag

a connection is being drawn: the pointer at at, over port / node over (0 = none)

Fields

from: u64

at: [f32; 2]

over: u64

ConnectCancel

the connection ended without a target (released elsewhere, Esc)

Waypoint

waypoint idx of edge goes to at; insert = add it at idx first (the first event of a drag from a middle handle); done = released

Fields

edge: u64

idx: u32

at: [f32; 2]

insert: bool

done: bool

WaypointDelete

remove waypoint idx of edge (double click on its handle, Esc after an insert)

Fields

edge: u64

idx: u32

Activate(DHit)

double click on a node / port / edge, Enter on the focused node

Context(DHit, [i32; 2])

right click, Shift+F10 or the menu key: at = window px (logical, for popups)

Delete

Del with a selection: delete st.sel

Click

a click on the background, or anywhere with DG_PLACE (snapped then); world units

Fields

at: [f32; 2]

DoubleClick

a double click on the background with DG_SELECT (no Shift, no Ctrl): the world point of the second press, not snapped; neither a Click nor a marquee follows it

Fields

at: [f32; 2]

ViewChanged

zoom or centre changed

Toggle(u64)

a click on the collapse button of a DN_TOGGLE node

Resize

the resize handle of a DN_RESIZE node was dragged: its new box x, y, w, h (world, the top left corner stays; at least 8 units); done = released (Esc: the box it had)

Fields

key: u64

rect: [f32; 4]

done: bool
